Mmm no you underestimate Pablo's bball IQ.
He did got nervous because he was aware that those two were much more athletic than him and could block him, so he decides to fake a layup (hence the jump - and you can see the fake is effective because Turner tries to steal the ball from him and the other one jumps to block him), and then to pass the ball backwards to his teammate.

Yea but JR hadn't crossed half court yet. If the Sixers would have hustled like they are supposed to, it would have been an easy steal. Either way, at the end of the day, whats more important is that it was a stellar defensive play on Prigioni's part.
